DISPENSING DEVICE Filed March so, 1951 Patented June 2%, 1333 TATES UNETE GEORGE S. HUNT, OF CHICAGO, ILLINOIS DISPENSING DEVICE Application filed. March 30, 1931.

This invention relates to dispensing devices, and has for an object the provision of a device which may be used for storing and r dispensing liquids such as gasoline and the like. It is particularly used for carryin and dispensing gasoline for small outboar motors, and for carrying an extra quantity of gasoline for automobiles and trucks. It may also be used by garages and filling stations for transporting a quantity of gasoline to cars on the road from which the supply of gasoline has been exhausted. WVith this device it is unnecessary to use a funnel as it now is with the ordinary can which is sometimes used.

Another obg'ect is the provision of a device from which the liquid may be easily exhausted by the use of a pump. The device is simple in construction and operation, and costs very little to maintain. Because of its simple construction, it may be manufactured at a very moderate cost.

Another object is to provide a device in 3 which the hose and its cap may be used as a closure for an orifice in the container.

Other objects will appear hereinafter.

In order to understand my invention more fully, reference may be had to the accompanying drawing in which:

Fig. 1 is a top plan view with certain parts broken away, and shows in dotted lines the manner in which the hose and nozzle may be anchored to a nipple in the top of the can when the hose is not in use;

Fig. 2 is a view partly in section and partly in elevation, taken substantially on the line 2-2 of Fig. 1, illustrating the pump of my device;

Fig. 3 is a detail view partly in elevation and partly in section, taken substantially on the line 33 of Fig. 1, and illustrates a method of attaching the nozzle and cap as shown in dotted lines in Fig. 1;

F i g. 4 is a detail view showing the plunger of the pump;

valve located in the lower end of the cylin der of the pump, and illustrates more particularly 110w the movement of the ball is limited.

The preferred form of my invention may be made by providing a container 10 having bail cars 11, bail 12, filler cap 13, filler orifice 14, threaded nipple 15, and cover 16. In order to provide a safer receptacle, container 10 may be made of rust resistant metal or may be leaded in order to provide the same result.

The pump of my device may be anchored in container 10 by the provision of acollar 17 secured to the cylinder 18. To the lowermost portion of cylinder 18 may be secured ball check valve 19, the ball of which is limited in its upward movement by means of ears 20, which are bent inwardly to prohibit the further upward movement of the ball of the valve from its seat. Beneath the ball valve may be provided screen 21 which may be held in place by means of lugs or cars 22. lVithin cylinder 18 may be provided a hollow plunger 23, which may in turn be provided at its lower extremity with a cap 24;, which has an orifice and a valve seat for the ball of the check valve contained in plunger 2%. Lugs 22 elevate the lower valve seat.

As is illustrated more particularly in Fig. 4, the plunger may have provided in its walls orifices 25, and may be provided internally with spurs 26 in order to limit the upper movement of the check valve, when the plunger is thrust downwardly into a full cylinder of liquid. Toward the lower end of plunger 23 may be provided bead 27 against which is adapted to rest metal gasket 28, below which is fiber gasket 29. It can be seen that cap 24 and bead 27 will hold the gaskets securely between them. Plunger 23 is provided at its other end with a stirrup handle 30. Cylinder 18 may be threaded at its upper extremity to receive an enlarged liquid discharge chamber or cap 31, which may in turn be provided with nipple 32, and which may also be provided with cap 33. Within cap 33 may be provided appropriate stuffing.

To nipple 31, which is appropriately beaded, may he aflixed hose 34. In the other end of hose 34 may be inserted pipe 35 which may be beaded at one end for the purpose of efiecting a more secure connection between the pipe and the hose. Intermediate the ends of pipe 35 is provided enlarged bead 36, which is adapted to seat in cap 37. The seating of head 36 in cap 37, in connection with appropriate packing, provides a liquidtight connection at this point, and also forms a connection in which cap 37 may be turned on pipe 35; cap 37 is also provided with laterally extending lugs 38 and internal threads 39 for engagement by the external threads of nipple 15 when pipe 35 is inserted in the nipple for the purpose of closing the vent provided by the nipple.

In operation liquid may be introduced into the container by removing filler cap 13, or by introducing the liquid in the vent provided by nipple 15. When it is desired to dispense the liquid from the container, it is necessary only to disengage the threads of cap 37 from the threads of nipple 15, and withdraw pipe 35 from the vent. Pipe 35 may then be inserted in the tank desired, and plunger 23 reciprocated by handle 30.

On the first upward stroke of plunger 23, no liquid will be expelled from hose 34, for the liquid occupies the space in cylinder 18 only, which has been filled by the unseating of the lower check valve in the cylinder when the plunger is drawn upwardly. \Vhen the plunger reaches its top-most limit, the lower check valve closes and leaves cylinder 18 filled with the liquid, but when the plunger is thrust downwardly, the liquid unseats the check valve in the base of the plunger, and further downward movement of the plunger forces the liquid into chamber 31, and thence outwardly through hose 34.

The device may be exhausted of liquid as it would be by the use of a siphon after the flow of liquid has been started, and pip-e 35 held at a point lower than the base of container 10; during this operation of course, plunger 23 must be raised to its upmost limit so that orifices 25 may empty into chamber 31. The two check valves will operate during this time to admit liquid through the lower check valve, and thence through the upper check valve into chamber 31. When a suflicient amount of liquid has been exhausted, the vent provided by nipple 15 may be closed by inserting pipe 34 and securing cap 37 to the threads of the nipple. 7

Certain variations in the construction and arrangement of parts may be made without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the precise details herein disclosed.

Having now described my invention, what- I desire to claim as new and secure by Letters Patent is:

said cap adapted to engage said threaded nipple.

In testnnony whereof I have si ned my name to this specificatlon.

GEORGE S. HUNT.
